Replacing the Controller Module(s): Single / Dual /
Simultaneous Upgrade
WARNING
Controller firmware
MUST
be identical for proper functionality.
DO NOT
mix controller modules from different models. Each controller has a unique
ID which is applied to host port names. As the result, you may encounter SAN
problems with identical port names on multiple systems.
When removing a RAID controller from a single-controller system, ensure that your
applications have been shut down beforehand.
Controller firmwares
MUST
match so before you replace a controller in a dual
controller system, please check if the firmware of the operational controller matches
the replacement controller sent to you. The replacement controller sent to you will
state its firmware version with a label on the packaging. To find out the firmware
version of your operating controller, use Storage Manager > Information > Enclosure
View in SANWatch (please refer to the SANWatch Manual for details).
To update the firmware, please refer to the following:
a. EonStorDS SANWatch User Manual on Upgrading the Firmware
b. Firmware Manual on System Functions: Upgrading Firmware
1. Prepare a clean, static-free work pad or container to place the controller.
2.
(Replacing single controller models or both controllers simultaneously)
Shut the system down.
Stop all I/O access to the system and make sure all
cached writes have been distributed to disk drives using firmware’s Main Menu
-> System Functions > Shutdown controller function.
turn off the power switches and unplug the power cords from PSUs
